The title of the song, which does not occur in the lyrics, is derived from Creque or Crequi (pronounced "creaky")[4] Alley,[5] home to a club in the Virgin Islands where the New Journeymen, John and Michelle Phillips' original group, spent time on vacation.[6] The lyric "Greasin' on American Express cards" refers to that time, during which they could only make ends meet by using their credit cards,[7] and the lyric "Duffy's good vibrations, and our imaginations, can't go on indefinitely" refers to Hugh Duffy, the owner of the club on Creeque Alley; Duffy later owned Chez Shack in Vieques, Puerto Rico.[8]
The Phillips' lyrics mention, directly or indirectly, many artists and bands who were part of the folk music scene at the time, including fellow band members Cass Elliot and Denny Doherty, Zal Yanovsky and John Sebastian of the Lovin' Spoonful, Roger McGuinn of the Byrds, and Barry McGuire of the New Christy Minstrels (the group had previously provided backing vocals for McGuire, including on the first recorded version of "California Dreamin'). Several locations important to the band's story are mentioned, such as the Night Owl Cafe in Greenwich Village. Michelle Phillips is referred to in the lyrics by her nickname Michi ("John and Michi were getting kind of itchy, just to leave the folk music behind"). John Phillips said that he wrote the song to tell their producer Lou Adler "who was who" in the band's history.[9]
The line that ends the first three verses is "And no one's getting fat, except Mama Cass". In the fourth verse, with the story of the genesis of the Mamas and the Papas nearing its denouement, Phillips changes the concluding line to "And everybody's getting fat except Mama Cass", with the word "fat" assuming the meaning of prosperous, alluding to the notion that the successes recently achieved by Cass' professional associates and friends had still eluded her. (During that Virgin Islands vacation, Cass became the last member to join the group when they were still known as the New Journeymen; the name change followed soon afterward.) The final line, "And California dreamin' is becoming a reality" is an apparent reference to their hit song "California Dreamin'", and marks the point at which the group achieved its breakthrough, leaving behind the lifestyle described in the rest of the song.
